It was discovered by Swiss astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland, on 5 September 1972.The asteroid orbits the Sun at a distance of 2.1–2.7 AU once every 3 years and 8 months (1,335 days). Its orbit is tilted by 6 degrees to the plane of the ecliptic and shows an eccentricity of 0.14. It has a well-defined rotation period of 11.0 hours. According to observations by the Wide-field Infrared Survey Explorer's NEOWISE mission, the body's surface has an albedo of 0.23, while the Collaborative Asteroid Lightcurve Link assumes a higher value of 0.40.1906 Naef is a vestoid or V-type asteroid, with its spectral type comparable to that of the group's namesake, 4 Vesta. V-type asteroids are less common than the abundant S-type asteroids, but they are similar in their stony composition, except for their higher concentration of pyroxenes, an aluminium-rich silicate mineral.The minor planet was named after Swiss banker Robert A. Naef (1907–1975) from Zürich, an ardent amateur astronomer, who produced the yearly observers almanac, Der Sternenhimmel, since 1940."@en }
